Sure, it's possible, but we are looking at a scenario where Bitcoin replaces the dollar.
I am a believer of Bitcoin becoming a world reserve currency one day, but a market cap of $200 trillion for all cryptocurrencies combined? No. There might not be enough extra liquidity in the world to support that claim. Where would all that wealth come from?
I believe Changpeng Zhao needs to go to the doctor and have his head examined.
you gotta trust in numbers when it comes to market cap because there is nothing else you can trust in when it comes to something that has no meaning.
people look at the number of coins and think 2000 is nothing but the reality when it comes to total marketcap is that the altcoins are being created at an alarming rate! I actually calculated the total number of coins in circulation 4 days ago and it was 18,992,064,409,496 (18 trillion) and today it is 19,045,916,973,830 (19 trillion). in other words a little less than 54 billion coins entered the circulation in only 4 days! considering that the average price of these <2000 altcoins excluding bitcoin is $179.36 that means $9,658,995,938,946 ($9.6 trillion) market cap was created in only 4 days!
you can calculate all of this using excel and coinmarketcap.com! and all of it is meaningless numbers.
He didn't mean the x1000 in literally sense, of course there could be some coins that go x1000 in the future but crypto space in general probably won't however he just made that number up just to show how hyped he is about the future of crypto. Maybe we should not take this word by word but just look at the general sense of what he wanted to say.
